The left part of the connecting rope 25 extends upward. The end of the connecting rope 25 extending upward is connected to the right rear part of the fixing member 16. In this way, when the fixing member 16 is rotated, the connecting rope 25 will be pulled, and the right part of the connecting rope 25 will pull the limiting plate 22 to move downward automatically.

[0036] When using the blood purification center pipeline tidying device, the blood purification center pipeline tidying device can be moved close to the side of the bed. The bed is placed in the following position: the head of the bed faces the left, the foot of the bed faces the right, and the patient's head lies at the head of the bed, so that the patient's left hand can be placed on the fixed frame 15. However, if hemodialysis is required for the patient's right hand, the blood purification center pipeline tidying device needs to be moved to the front of the bed, and the rotating plate 13 needs to be rotated 180°, so that the rotating plate 13 rotates and drives the moving plate 14 to rotate 180°, and the moving plate 14 rotates 180° and drives the fixed frame 15 to rotate 180°, and the fixed frame 15 faces the patient's right hand.

When the limiting plate 22 moves downward, it will drive the extrusion member 4 and the buffer spring 41 to move downward. After the bottom of the extrusion member 4 contacts the upper part of the pipeline, under the action of the buffer spring 41, the extrusion member 4 can maintain the state of pressing the upper part of the pipeline, thereby better pressing the upper part of the pipeline. When the limiting plate 22 moves upward and resets, the limiting plate 22 will drive the extrusion member 4 to move upward and reset, and the extrusion member 4 drives the buffer spring 41 to move upward and reset.

The limiting member 5 is slidably connected to the left and right sides of the fixing member 16, and the limit member 5 and the limiting screw rod 52 are threadedly connected.

[0043] After the fixing member 16 is rotated forward and downward to close, the medical staff can manually limit the screw rod 52. The rotation of the limiting screw rod 52 will drive the limiting member 5 to move in the direction away from the fixing member 16, and the limiting member 5 will clamp the patient's hand. In this way, the position of the limiting member 5 can be adjusted by rotating the limiting screw rod 52, so as to fix arms of different thicknesses, thereby preventing the patient's hands from moving around and affecting hemodialysis.
